2.4 Inlet
Operating Instructions
Version 1.5
2.4 Inlet
2.4.1 Optical fibre sensor at the inlet area
Fig. 2-1 Optical fibre sensor at the inlet
Fig. 2-2 Optical fibre sensor at the inlet
The plant has an optical fibre sensor
at its inlet. This optical fibre sensor
is used for PC board identification.
The specified set-point value of this
sensor is between
100 - 250 digits.
Rehm Thermal Systems techni-
cians preset the switching threshold
to 350 digits for a single track and
500 digits for a dual track.
The PC board will be detected when
the threshold level is exceeded.
The degree of soiling is determined
as a percentage. An alarm will in ad-
dition be triggered in the display
should this approach the threshold
level.
To continue proper operation, the
sensor should then be cleaned as
soon as possible, using an appropri-
ate cleaning agent.
The settings are based on Rehm
Thermal Systems experience.
